[0002] Cable is a wire product used to transmit electrical energy. The structure of the cable is mainly divided into a core, an insulation layer, a shielding layer and a protective layer. The remaining structure is added according to the model and usage of the cable to enhance the performance of the cable. When a cable fails, the insulation layer, shielding layer and protective layer outside the core need to be stripped off for easy maintenance.

[0003] However, there are still the following deficiencies when stripping and repairing cables: 1. When stripping the cable, it is usually cut with a handheld knife. However, since the cable skin is arc-shaped, the staff often need to hold the cable with one hand and hold the knife with the other hand to cut. It is not easy to apply force during operation, which poses certain safety hazards. 2. For some large-diameter cables, the surface is very hard, and the manual cutting method with a handheld knife often cannot effectively cut the cable skin, and the cutting efficiency is extremely low, which affects the cable maintenance efficiency; 3. When stripping outdoor cables in cold weather, not only does the cable surface become extremely hard and smooth after freezing, but the cutter also becomes brittle after being cooled, which makes cutting time-consuming and laborious, and the cutter is prone to slippage, and in severe cases, it may even cause the cutter to break; Therefore, there is an urgent need for a power cable fault repair device that can overcome the above-mentioned shortcomings.
